On Amsteel 7/64" or larger soft shackles, I definitely don't see the need. In fact, I prefer to make my Amsteel soft shackles out of 1/8" because they're easier to open.
On Zing-It 1.75 soft shackle prusiks, I also haven't found the need because it is very rare that I disconnect the soft shackle prusik from the ridgeline. In my experience, the eye only becomes hard to open after repeated opening, and I don't do that much with my soft shackle prusiks.
Thank you gentlemen. SilvrSurfr, that's what I was asking and thank you. Dutch, sorry for the confusion, but, that is also welcomed info.
Enjoy and have fun with your family, before they have fun without you
